Frequently Asked Questions

Why is the black the cheapest cartridge in the TN436 family?

Volume economics, visible in the list prices themselves. The TN436BK lists at $299.99 and sells here at $199.99, while each colour — TN436C, TN436M, TN436Y — lists at $332.64 and sells at $237.60. Every cartridge in the family is rated at 6,500 pages, so the black's lower price is not a capacity difference: black is the cartridge every one of these machines consumes most, it is manufactured and stocked in the greatest numbers, and Brother's pricing reflects that. For buyers the effect is welcome — the slot you refill most often is the cheapest to run, at about 3.1 cents a page.

How long does 6,500 pages of black last in a department?

Long enough to change how you think about reordering. A workgroup printing 1,500 black pages a month gets over four months from one TN436BK; at 3,000 pages a month — a busy department on an HL-L9310CDW-class machine — around two months. Set against the standard-yield cartridges these printers also accept, the high-yield black roughly halves the number of times a year someone has to stop, swap and dispose. In a shared office, that reliability is worth as much as the per-page saving.

Which printers take the TN436BK?

Six models: the HL-L8360CDW, HL-L8360CDWT and HL-L9310CDW printers, and the MFC-L8900CDW, MFC-L9570CDW and MFC-L9570CDWT all-in-ones. It fills the black slot only, working with the TN436C, TN436M and TN436Y colours. These machines also accept the platform's lower-yield cartridges, and the classes can be mixed slot by slot — but read the label of the cartridge you are removing before ordering, because if it reads TN436BK, this is the cartridge your printer is expecting to see again.

Is $199.99 a fair price for a cartridge with a $299.99 list price?

On a genuine-for-genuine comparison, yes: you are paying $100.00 under Brother's list for the same factory-sealed TN436BK, from a platform whose cartridges sit in premium territory wherever genuine stock is sold. The comparison that matters is against other genuine listings, not against the compatible versions of this code, which are different products at different prices and are listed separately on this site. A supposed genuine TN436BK offered far below this level deserves suspicion — at a deep enough discount, what ships is usually not a sealed Brother unit.

My pages are fading evenly across the sheet — toner, or something else?

Even fading that arrives gradually is the toner cartridge's signature: the TN436BK is running dry, and rocking it gently side to side before refitting will usually deepen output briefly while the replacement travels. Faults that survive a cartridge change — repeating marks at regular intervals, background shading, streaks in the same position on every page — belong to the machine's drum unit or another internal component, not to this cartridge. Swapping the black first is still the right diagnostic order: it is the cheapest test, and nine times out of ten it is also the cure.

How do returns and warranty work on this cartridge?

The TN436BK is returnable for 30 days in all cases, and its warranty cover is Brother's manufacturer warranty, as with all genuine Brother products we sell — the full terms are on our shipping and returns page. OEM stock runs on those terms; the extended cover described elsewhere on this site belongs to compatible cartridges. A faulty cartridge should be raised with support Monday to Friday, 9 AM to 5 PM CST, inside the 30-day window.
